   Die vorliegende Erfindung bezieht sich auf eine Umlaufschmierung für solche elektrisch direkt angetriebene Schleudern, bei denen in bekannter Weise der Rotor des antreibenden Elektromotors auf einer Hohlwelle sitzt, die die frei   einstellbare Zentrifugenspindel mit   Spiel umgibt und auf diese die Drehbewegung mittels eines Kugelgelenkes überträgt. Bei dieser Art von   Schleudern muss   das   Schmiermittel   nicht nur ins Innere der Hohlwelle zwecks Schmierens des Kugelgelenkes bzw. der Spindellagerung,

  Circulating lubrication for electrically operated strollers.



   The present invention relates to a circulating lubrication for such directly electrically driven centrifuges, in which the rotor of the driving electric motor sits in a known manner on a hollow shaft that surrounds the freely adjustable centrifuge spindle with play and transfers the rotary motion to it by means of a ball joint. With this type of spin, the lubricant not only has to go inside the hollow shaft for the purpose of lubricating the ball joint or the spindle bearing

In the drawing, two versions of the lubricating device according to the invention are illustrated in section, u. Between. Fig. 1 shows one with a high-lying lubricant container and Fig. 2 shows a device in which the lubricant is rotated with the aid of a steering wheel.



   The slingshot has a housing e, which carries the stator of an electric motor, the rotor b of which sits on a central hollow shaft a designed at the lower end to form a friction clutch (for example a multi-disk clutch), which surrounds the spindle f of the slinger with play, which on the ball -
